TRANSFER DEVICE AND TRANSFER METHOD
Document Type and Number:
Japanese Patent JP2014155032
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To increase the efficiency of transfer processing.SOLUTION: In a transfer device 104, an SMC-U 205 stores session information S in a memory 206 when a session generation request REQ is received from a session request source. The transfer device 104 transmits, to the request source, a session generation response in which C-Plane TEID and U-Plane TEID are buried. The transfer device 104 caches, into a memory 210, the session information S stored in the memory 206. When a user plane packet 220 is received by a NIF 201, the transfer device 104 refers to the session information S cached into the memory 210 and has a header of the user plane packet 220 converted by the NIF 201. The NIF 201 transfers, to the destination, the user plane packet 230 which has had its header converted.
